Abstract
OBJECTIVE: This study aimed to examine the prevalence of overvaluation of shape or weight in a nationally representative sample of U.S. adults with binge-eating disorder (BED) and to compare functioning correlates using a group of adults with bulimia nervosa (BN). METHODS: Participants included 207 respondents from the National Epidemiologic Survey on Alcohol and Related Conditions who met Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) diagnoses of BED (n = 163) or BN (n = 44). Sociodemographic characteristics and functioning were compared in BED with overvaluation (BED+OV), BED without overvaluation (BED), and BN. RESULTS: Approximately 50% of BED respondents reported overvaluation. Mean age was lower in BN than BED. Mean BMI was lower in BED+OV than BED and higher than BN. A greater proportion of BED+OV reported functional impairment than BED. BN was more likely to report "serious problems doing daily tasks" than BED and less likely to report "impairment in normal activities" than BED+OV. BN reported significantly lower mental functioning than BED. CONCLUSIONS: Findings based on this nationally representative sample are that overvaluation was associated with greater functional impairment within BED, and BED+OV reported greater impairment than BN in interference with normal activities but less impairment related to mental health. The increased impairment associated with BED+OV provides support for overvaluation as a diagnostic specifier for BED.
